Zhu Yuanzhang was the founding emperor of the Ming Dynasty, and a poor man turned over and became emperor. In this process of turning over, he can't do without the help of many talented people, many of whom are founding heroes. However, Zhu Yuanzhang did not thank these heroes when he ascended the throne, but began to hunt them down. Among them, Zhu Yuanzhang also set up an organization to complete this matter.
If we say that the greatest pursuit of heroes in the Ming Dynasty is the "aquamarine case", aquamarine is the founding star and hero of the Ming Dynasty. Later, Zhu Yuanzhang arrested Aquamarine on the charge of "weeding". The number of people involved in this case was as high as 15,000, and many founding heroes were also involved. Because of the large number of people, there are many natural escapes, so the secret organization established by Zhu Yuanzhang is to hunt down these fugitives. One of aquamarine's sons escaped. As the son of the key person in this case, he became the key target of this secret organization.
Because this case was triggered by aquamarine, this organization was also established in this case. Later, Zhu Yuanzhang directly named this organization "Tuyumen", which means the organization that slaughtered all relatives and friends of Guan Yu Aquamarine. Tu Youyou Gate members are ruthless and numerous. After Zhu Yuanzhang's death, Tu Youyou Gate still didn't stop working and continued to hunt. Later, they got the news that Aquamarine's son might be in northern Anhui, and finally they set the target here.
Later, a note was drawn at the crime scene, "In the Spring and Autumn Period, more than 10,000 people were killed. Inherit the roots of our generation and don't teach the wind to blow the green door. " Judging from this, this murder is inseparable from Tu Youyou Gate.
